Authenticated Sports Memorabilia
Curated around Spurs and Texas teams.
Charity Auction Fundraising Company in San Antonio
Diamonds in the Rough provides authenticated sports and music memorabilia, plus the bidding tools to sell it, to charity auctions across San Antonio and the surrounding Hill Country. Your beneficiary receives guaranteed funds from the first bid, and 100 percent of everything above that goes straight to your cause. Since 2011 we have helped organizations raise more than $17 million, supporting over 600 events a year.
Memorabilia San Antonio Bidders Actually Want
A signed jersey only drives bidding if the room cares about the name on it. In San Antonio, few cities in the country have a deeper connection to one team than this one has to the Spurs, and Spurs memorabilia anchors most rooms here. We curate around that local passion rather than a generic national catalog, because it is what turns a polite bid into a bidding war. For crowds that run broader than sports, we bring framed guitars, signed vinyl, and music memorabilia as well.
How It Works, and Why There Is No Risk to Your Organization
We bring the inventory, hand-selected and fully authenticated. Your beneficiary is guaranteed proceeds starting with the very first bid, and anything the items sell for above that guarantee goes entirely to your cause. Your committee does not buy inventory, front costs, or carry unsold items.
